Thanks to Monk for a superb challenge.
Plenty of fun in Monk’s puzzle this morning. A great mix of complex clues to mull over, and much simpler ones. I thought 3d was a particularly standout clue. And we have the name of the publication coming down two rows – neat!

Yes very entertaining and doable. Completely missed the Nina, as usual, but it’s a banger. Loved the double Barry Humphries references. Liked emptily, emphysema, flea pit. Thanks both.
Yes, thought there might be more about Sir Les and Dame Edna, but not that icn see. Hadn’t heard of a dime museum or a rhyme royal either. And had forgotten the name of that WWII operation [had it not been for Hitler’s hubris and Stalin’s ruthlessness, well, who knows …]. Lots to learn, remember and enjoy, thanks Monk and Oriel.
